DETAILED DESCRIPTION OF THE PRESENT INVENTION
Referring now to drawings, Figs 1-3 show a clutch actuator assembly 10 comprising a frame 1 l and a pedal guard 12 containing a complete assembly including a pedal 14 which is adapted to activate a push-pull flexible cable 13, one end of which is fastened at the clutch system (not shown ) and the other end is connected to the pedal system. The cable 13 is encased in a flexible casing 16 which is also fixed, one end at a bracket (not shown) in proximity to the clutch system and the other end at the frame 11 of the foot pedal l4 by means of casing 16 and nut 15.
The cable 13 can now operate freely within the casing between the pedal 14 and the clutch and is not exposed to accidental engagement.
The pedal 14 is specially designed with a levered arrangement to relieve the additional pressure caused by the friction of the cable 13 within the casing 16 and required by the operator on the foot pedal 14. The pedal 14 is pivoted from non-operative position shown on Fig. 2 to an engaged position shown on Fig. 3 by means of a pivot 34 mounted in the frame 11 by means of bushings 40, shoulder screws 38, rings 42 and hinge pins 44. To facilitate smooth activation of pedal 14 engaging clutch by means of cable 13, the pedal 14 is provided with an assembly comprising a bracket 20 mounted under the middle section of the pedal 14 by means of screws 36.
Two downwardly oriented links 24 are pivotally mounted on the bracket 20 by means of link pins
4 22, bushings 40 and rings 42. Lower ends of links 24 are connected between each other by means of shaft 28 provided with two symmetrically located rollers 26 which are mounted adjacent to respective ends of the shaft 28. The rollers 26 are adapted to roll over a ramp 18 mounted on a bottom portion of frame 11 just below the bracket 20. As it is clearly shown on Figs 2 and 3, ramp 18 has in cross-section a configuration of a step rounded downwardly and provided to facilitate a gradual rolling motion of rollers 26 engaging the ramp I 8 when the user steps on pedal 14 to engage the clutch. As it is shown on Fig. 5, one end of cable 13 is attached to the shaft 26 by means of a jam nut 30. When the pedal 14 is activated, cable 13 is pulled forward due to the forward motion of the shaft 28, and rollers 26 roll forward downwardly over the ramp 18. Such forward movement of the end of the cable I 3 actuate the clutch of the machine into operative mode.
Figs 9-26 show the second embodiment of the present invention comprising the clutch actuator assembly 10 also encased into the protective housing 12 and provided with another variant of the pulling means 72 better shown on Figs 20-26. In this embodiment pedal 14 is also mounted on the base platform 11 by means of pedal arms 46 pivotally connected by means of pedal pivot shaft 34 to a pedal support 47 extending vertically from the base portion 1 1. Pulling means 72 are mounted undenleath of the pedal 14 on the predetermined distance from the pivot 34. Such distance is chosen to allow the most efficient operation of the pedal assembly and is substantially in the range between 1/4 and 1/2 of total distance between the foot engaging portion 17 and the pivot shaft 34. However, the present invention is not restricted to such position of the pulling means and other variants are possible without departing from the scope of the invention.
Pulling means 72 of second modification comprises two symmetrically located cam actuators 48 pivotally mounted on the base platform 11 by means of cam pivot axis 52 and cam supports 58. Each of cam actuators 48 is provided with a pedal engagement means or roller bearings 50 mounted on cam actuators 48 by means of shoulder screws 54 . Those roller bearings 50 are extending outwardly from cam actuators 48 to facilitate rotatable engagement of said roller bearings 50 with a roller ram portions 62 located underneath of the pedal 14 (see Fig. 18). Cam actuators 48 are pivotally connected to a cable holder assembly including cable holder shaft 74 spaced between cam actuators 48 and a cable holding bolt 56 provided with nut 78 (see Fig. 25).
Cable holder assembly is connected to the cable 13 (see Fig. 18) encased into the outer protective sleeve or casing 16. Another end of the cable 13 is remotely connected to the clutch actuator of a machine (not shown) by means of bracket 64, adaptor 66 and tip 68 (see Fig.
19). A spacer shaft 82 is mounted between lower ends of cam actuators 48 by means of bearing bushings 84 to keep a
Figs 9-26 show the second embodiment of the present invention comprising the clutch actuator assembly 10 also encased into the protective housing 12 and provided with another variant of the pulling means 72 better shown on Figs 20-26. In this embodiment pedal 14 is also mounted on the base platform 11 by means of pedal arms 46 pivotally connected by means of pedal pivot shaft 34 to a pedal support 47 extending vertically from the base portion 1 1. Pulling means 72 are mounted undenleath of the pedal 14 on the predetermined distance from the pivot 34. Such distance is chosen to allow the most efficient operation of the pedal assembly and is substantially in the range between 1/4 and 1/2 of total distance between the foot engaging portion 17 and the pivot shaft 34. However, the present invention is not restricted to such position of the pulling means and other variants are possible without departing from the scope of the invention.
Pulling means 72 of second modification comprises two symmetrically located cam actuators 48 pivotally mounted on the base platform 11 by means of cam pivot axis 52 and cam supports 58. Each of cam actuators 48 is provided with a pedal engagement means or roller bearings 50 mounted on cam actuators 48 by means of shoulder screws 54 . Those roller bearings 50 are extending outwardly from cam actuators 48 to facilitate rotatable engagement of said roller bearings 50 with a roller ram portions 62 located underneath of the pedal 14 (see Fig. 18). Cam actuators 48 are pivotally connected to a cable holder assembly including cable holder shaft 74 spaced between cam actuators 48 and a cable holding bolt 56 provided with nut 78 (see Fig. 25).
Cable holder assembly is connected to the cable 13 (see Fig. 18) encased into the outer protective sleeve or casing 16. Another end of the cable 13 is remotely connected to the clutch actuator of a machine (not shown) by means of bracket 64, adaptor 66 and tip 68 (see Fig.
19). A spacer shaft 82 is mounted between lower ends of cam actuators 48 by means of bearing bushings 84 to keep a
5 distance between cam actuators 48.
In operation the clutch actuator is activated or engaged by pulling means 72 which are provided to facilitate engagement of the clutch by a pulling action of the flexible cable 13, wherein the pulling action of the cable 13 is facilitated by transferring of a leverage movement of the pedal 14 into a pulling force of the pulling means 72 activated by the pedal 14 during leverage movement of the pedal. This operation is better seen on Fig. 18 showing by arrows directions of movements of all interacting parts of the assembly of the present invention.
In this case when the operator engages the foot portion 17 of the pedal 14, the pedal 14 will pivotally move downwardly engaging by its roller ramp portions 62 a pedal engaging means or roller bearings 50. Roller bearings 50 in turn will roll along roller ramps 62 and cause cam actuators 48 to move pivotally such a way that both roller bearings 50 together with the one end of the cam actuators 48 will go downwardly towards the base portion 11. Such movement of cam actuators 48 will cause the forward movement of the cable holder assembly in the direction towards the foot engagement porting 17. The forward movement of cable holder assembly will create the pulling force causing the pulling of the cable 13 and, as a result, activation of the clutch actuator connected to another end of the cable 13. The pulling action of the cable 13 is provided by a rotational movement of cam actuators 48 activated by the leverage movement of the pedal 14.
Such arrangement of roller bearings 50 adapted to rotatably engage roller ramp portions 62 of the pedal 14 facilitates a smooth and easy movement of the cable 13 within the protective outer sleeve 16, wherein the protective outer sleeve 16 acts as a guiding channel provided to maintain the position of the cable 13 within the sleeve 16 and to permit unrestricted co-axial movement of the cable 13 within the sleeve 16. In this case sleeve 16 remains substantially without any co-axial movement during activation of the cable l 3 by the pulling means 72, which is an advantage of the present embodiment.
Preferably, protective outer sleeve is made of a rigid steel shell protected by a rubberized
In operation the clutch actuator is activated or engaged by pulling means 72 which are provided to facilitate engagement of the clutch by a pulling action of the flexible cable 13, wherein the pulling action of the cable 13 is facilitated by transferring of a leverage movement of the pedal 14 into a pulling force of the pulling means 72 activated by the pedal 14 during leverage movement of the pedal. This operation is better seen on Fig. 18 showing by arrows directions of movements of all interacting parts of the assembly of the present invention.
In this case when the operator engages the foot portion 17 of the pedal 14, the pedal 14 will pivotally move downwardly engaging by its roller ramp portions 62 a pedal engaging means or roller bearings 50. Roller bearings 50 in turn will roll along roller ramps 62 and cause cam actuators 48 to move pivotally such a way that both roller bearings 50 together with the one end of the cam actuators 48 will go downwardly towards the base portion 11. Such movement of cam actuators 48 will cause the forward movement of the cable holder assembly in the direction towards the foot engagement porting 17. The forward movement of cable holder assembly will create the pulling force causing the pulling of the cable 13 and, as a result, activation of the clutch actuator connected to another end of the cable 13. The pulling action of the cable 13 is provided by a rotational movement of cam actuators 48 activated by the leverage movement of the pedal 14.
Such arrangement of roller bearings 50 adapted to rotatably engage roller ramp portions 62 of the pedal 14 facilitates a smooth and easy movement of the cable 13 within the protective outer sleeve 16, wherein the protective outer sleeve 16 acts as a guiding channel provided to maintain the position of the cable 13 within the sleeve 16 and to permit unrestricted co-axial movement of the cable 13 within the sleeve 16. In this case sleeve 16 remains substantially without any co-axial movement during activation of the cable l 3 by the pulling means 72, which is an advantage of the present embodiment.
Preferably, protective outer sleeve is made of a rigid steel shell protected by a rubberized
6 and reinforced coating provided to facilitate an oil and dirt resistance in use. Flexible cable 13 is made of steel. The length of the cable could be variable in so far the friction in the cable is not overcame by the mechanism of the pedal.
It must be emphasized that the present invention is not restricted to the pulling means described above, and any other equivalents performing the same function with the same result are also within the scope of the present invention.
The advantages of the clutch actuator assembly of the present invention is complete protection of the pedal 14 against any accidental engagement, the possibility of using such assembly with a wide range of machinery, easy installation, low maintenance, and relatively cheap costs.
The most important advantage ofthe present invention is the fact that overall assembly is a very strong but flexible means to transfer the force to the remote location wherein the use of flexible cable eliminates the fixed and rigid mechanisms often used on punch presses. Such advantageous arrangement of the present invention eliminates the use of a solenoid or pneumatic actuators, but in the same time permits a comfortable position of the operator.
The leverage movement of the pedal is not only means of pulling the cable, but it is the most effective way to simply pull a cable within the protective sleeve without moving the cable in any unwanted position.
The roller ramp allows to give a feedback to the operator giving the advantage of controlling the "feel or feedback" to the operator. The shape of the roller ramp allows to control the speed and acceleration of the cable within the protective outer sleeve and to let the operator know or "feel" the proper clutch engagement.
Thus, it can be seen that the objects of the present invention have been satisfied by the structure presented hereinabove. While in accordance with the Patent Statutes, only the best mode and preferred embodiments of the present invention have been presented and described iii detail, it is to be understood that the invention is not limited thereto or thereby.
Accordingly, for an appreciation of the true scope and breadth of the invention, references should be made to the following claims.
